Report #54480

[research] Agent evals conflate tool selection accuracy with tool argument accuracy, masking whether the agent knows what to do but not how

Separate evals into two distinct metrics: 1\) Tool Selection Accuracy \(did it pick the right function?\) and 2\) Argument Schema/Value Accuracy \(did it pass the right params?\).

Journey Context:
A common mistake is a binary tool call success eval. If an agent calls search\(query='...'\) instead of lookup\(id='...'\), that is a planning error. If it calls lookup\(id='invalid\_format'\), that is an extraction error. Fixing planning requires prompt changes; fixing extraction requires better few-shot examples. Separating the metrics directs debugging.
